Levitt set a trial date of Sept. 17 for Hoeller, with a case management scheduled for Aug. 29.

At the request of the defense attorneys, Levitt also agreed to schedule a 402 conference between himself, prosecutors and defense attorneys. A 402 conference is a private meeting in front of a judge to discuss a possible plea deal resolution to the case. When asked by Levitt, Hoeller said he wanted officials to proceed with the conference.

Hoeller is accused of sending a threatening letter to Weinstein in February referencing a high school shooting that occurred that month, killing 17 people in Parkland, Fla.

Officials said the letter was copied to several other Lake County government officials.

Authorities said Hoeller wrote that he was unhappy with a recent electronic filing he made at the Lake County Circuit Clerk's Office.

The letter said that Hoeller was getting anxiety from trying to work with the Circuit Clerk's Office, and that it was getting to the point at which someone might act out in a similar manner as the mass shootings in Parkland, Orlando and Las Vegas, Weinstein said earlier this year.

She said the letter also mentioned county staff's safety while walking to their cars.

Amen said after Hoeller’s arraignment the whole situation stemmed from a dispute over $75, and that Hoeller had been told by the Illinois Attorney General’s Office that he should not have had to pay the circuit court filing fee in question.

Hoeller remains in the Lake County jail with bail set at $750,000.

Hoeller had sent about five letters in the moths prior to the February communication, Weinstein said. Each letter had been escalating in nature, as had his behavior when he came into the Circuit Clerk's Office, she said.

Weinstein said her primary concern has been for her staff's safety, as well as her own. She's been working to increase security at its offices, and the office recently improved the camera systems at the branch courts.

According to the Lake County Sheriff’s Office, Hoeller stated that he intended to "scare" the recipients of the letter.
